Compact Dry EC is a medium for E.coli and coliforms. Coliform bacteria are considered indicator germs for faecal contamination. E. coli is the best-known representative of the coliform group and is considered an indicator for the presence of other pathogenic organisms. The medium contains two kinds of chromogenic enzyme substrates: Magenta-Gal and X-Gluc. E.coli forms blue colonies. The total coliform group count is the sum of both the red and blue colonies.
